msnodesql is working out great for me. Here is a sample:

var mssql = require('msnodesql'), 
    express = require('express'),
    app = express(),
    nconf = require('nconf')

nconf.env()
     .file({ file: 'config.json' });

var conn = nconf.get("SQL_CONN");   
var conn_str = "Driver={SQL Server Native Client 11.0};Server=server.name.here;Database=Product;Trusted_Connection={Yes}";

app.get('/api/brands', function(req, res){
    var data = [];
    var jsonObject = {};    

    mssql.open(conn_str, function (err, conn) {
        if (err) {
            console.log("Error opening the connection!");
            return;
        }
        conn.queryRaw("dbo.storedproc", function (err, results) {
        if(err) {
                   console.log(err);
                   res.send(500, "Cannot retrieve records.");
                }
       else {
             //res.json(results);

             for (var i = 0; i < results.rows.length; i++) {
                 var jsonObject = new Object()
                 for (var j = 0; j < results.meta.length; j++) { 

                    paramName = results.meta[j].name;
                    paramValue = results.rows[i][j]; 
                    jsonObject[paramName] = paramValue;

                    }
                    data.push(jsonObject);  //This is a js object we are jsonizing not real json until res.send             
            } 

                res.send(data);

            }       
        });
    });
});
